Getting ready to get a front end kit (?) or seperate parts with tubular upper A-arms, USA parts (hopefully) and manual discs. 15" or 14"?? I realize w/ 15's I'll get bigger brakes, better wheel selection, etc. What fits, works best? Have looked at a few in mags. Not sure what's the best way to go. Any advice appreciated. 65 FS, 273, 4-speed, currently 14" wheels/drums all around. Thanks, John
